For the Riders, the loss of key players on defense will be something to watch. Larry Dean was supposed to be the replacement for Elimimian and Freddie Bishop for Charlston Hughes. I believe they have some up and comers on defense but still some tough blows before the season even begins.
On offense, they've lost some key guys on the o line. That'll be interesting to see but they've also brought in some studs as well. I expect a more explosive offense with Jason Maas as their OC.
